please help answer in full its one big question

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 27 couples. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of 27 births. ....Y The value of the mean is p = (Type an integer or a decimal. Do not round.) The value of the standard deviation is o = (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separat ficantly low or significantly high. Values of girls or fewer are significantly low. less than (Round to one decimal place as needed.) Values of girls or greater are significantly high. greater than (Round to one decimal place as needed.) equal to c. Is the result of 25 girls a result that is significantly high about the effectiveness of the method? V significantly high, because 25 girls is girls. A result of 25 girls would suggest that the method The result (Round to one decimal place as needed.) Enter your answer in each of the answer boxés.
